i915: Use Y tiling for textures
This basically reverts commit 2acc7193743199701f8f6d1877a59ece0ec4fa5b. With the previous change, we're not batchbuffer limited any longer. So we actually start seeing a performance difference between X and Y tiling. X tiling is funny because it is faster for screen-aligned quads but slower in games. So let's use Y tiling which is 10% faster overall.
